High speed paper web turn-up system with a prepared length paper band coil

Abstract

An improved paper band delivery assembly for reliable high speed delivery of a turn-up paper band across a moving web of paper being wound onto a spool. The turn-up paper band is made ready for a turn up procedure by coiling a predetermined length of paper band suitable for a particular machine and retaining the coiled paper band in a reservoir pending deployment across a spool for a turn up procedure. The paper band may be coiled via manual operation or via automated operation. Coiling apparatus may be modularly replaced on a paper making machine. The coiled paper band may be supported within the reservoir on rollers, pins, or other items conducive to fast and reliable uncoiling.

AI Technical Summary

Benefits of technology

The present invention aims to improve the process of paper band deployment in an industrial paper machine. By eliminating the loop box, the invention enables faster and more reliable turn up process times and consistent transfer of a moving paper sheet from being gathered on a full paper machine spool to being rolled onto an empty paper machine spool. Additionally, the invention provides methods and apparatus for repairing malfunctioning portions of a paper band dispenser without inhibiting the operation of a paper spooling machine. An operator has the option to use either the automated dispensing module and a manual dispensing module during a particular turn up process as primary and secondary dispensing modules. Furthermore, the invention provides apparatus and methods for rapid change out of sub-components of a primary or secondary module while maintaining functionality of the other module.

Problems solved by technology

Failure in a turn up process may result in converting moving paper to scrap and halting of the paper machine involved.

Deployment of paper band from a loop box has constraints on how fast the paper band may be deployed without jamming, and even if deployed slowly paper band known to jam in the loop box.

Consequently, known turn up processes have inherent risks that diminish efficiency using the paper making machine.

A failure of an apparatus or system used to dispense transfer turn-up tapes often results in prolonged failure of transfer of paper product produced by a running paper machine to a new spool, which in turn results in one or more of: decreased production, inconsistent winding of the paper product, inconsistent roll sizes, excessive waste, shorter service life of equipment, and unsafe operating conditions.
